Evaluating fractions
I’m looking at a math problem involving fractions. It seems like the first numerator might be a 3, but I’m a bit confused since I see \(-\frac{?}{5}\). The result for \(-\frac{3}{5} + \frac{5}{3}\) appears to be \(-8/15\), which doesn’t seem right upon recalculating. Instead, I get a proper sum of \(\frac{16}{15}\). It looks like there’s a misunderstanding about multiplying numerators, and I have to infer the original examples written.Considering visible items
I’m thinking about the third item, “В: 3/2,” and whether there’s another item to solve. Maybe it's necessary to address all the visible integer lines too? However, I'm not really sure what the clear condition is for this. It's a bit unclear at the moment, and I'm pondering how to proceed effectively. I wonder if there's a simpler way to tackle this!
На фото видно несколько примеров. Какой именно решить: \(\frac{3}{5}+\frac{5}{3}\), \(\frac{1}{2}+\frac{3}{8}\) или другой?
